1933 Goudey

1933 Goudey baseball cards were issued during the worst part of The Great Depression. The set ended up at 240 cards (239 printed in 1933 and one in 1934). In an effort to attract collectors, several of the games top players were honored with multiple cards including "The Great Bambino" who appeared on 4 different cards.
The Babe was once asked why he made more than the President of the United States, the Babe answered simply: "I had a better year than he did."

The Elusive Nap Lajoie
One of the most important facts regarding the 1933 Goudey set was their infamous marketing ploy. Goudey took "marketing" to a whole new level to keep people buying packs by never issuing card #106. Collectors wrote the Goudey Card Company complaining. They were rewarded with Goudey sending them the un-issued card #106 (Nap Lajoie) in 1934.
